A fast-moving storm could bring 0.25 inches to 0.50 inches of rain to San Diego this weekend, along with a dusting of snow to the county’s highest mountain peaks.

The National Weather Service says the system will blow ashore late Saturday and could produce scattered rain before midnight. But the heaviest rain will fall overnight and into the morning hours.

Inland valleys and foothills are more likely to receive between 0.50’’ inches and 1 inch of rain.

The daytime highs will be on the cool side: 62 degrees on Saturday and Sunday.

The surf will build going into the weekend, especially in South County. The favored spots will get 4- to 5-foot waves by afternoon, and sets up to 8 feet on Saturday. The waves could peak at 10 feet on Sunday. But the storm will produce gusty winds Saturday and Sunday, making for choppy conditions. The winds could reach 20 mph or higher near the coast and twice as fast across inland foothills and mountains.
